My left thumb started feeling numb about 6wks ago.  About a week after that my right index finger started feeling numb also.  I can use both normally and have feeling in them; they both just feel numb.  Sometimes is much more significant than others.  I can't think of any change that might've caused this ie: no injury, change in work, stress etc.  I will be seeing a doctor in a few weeks but any thoughts would be appreciated.
